From Chu Yuxiao's perspective, he could only see the Fake Empress's back and couldn't see at all what she was doing.
But he could guess, she was absorbing the True Empress's essence.
He had also heard that some demons, in order to impersonate someone, would change their appearance and scent by absorbing that person's essence.
However, it generally could only be maintained for a few days, after which they would need to absorb more.
Just as the Fake Empress had just said, only after continuously absorbing for four hundred and forty-nine days would their appearance no longer change.
If they wanted to impersonate another person the next time, they would have to use the same method.
In short, demons that changed their appearance by absorbing someone else's essence either had no human form or were incredibly ugly.
Otherwise, they would lose their own appearance and could never change back.
